Does using mobile phones affect myopia?

With today’s rapid development, life has become increasingly intelligent and advanced. For instance, the continuous advancement of technology—particularly smartphones and other electronic devices—provides abundant information, enabling people to stay at home comfortably. However, this convenience also brings numerous health concerns. So, does smartphone use affect myopia?

Does smartphone use affect myopia?

Yes, smartphone use does affect myopia. “Using smartphones for entertainment” implies prolonged, rather than brief, usage—not merely functional but recreational. Gaming sessions may last for hours, and some individuals even play all night. Prolonged close-range smartphone use causes spastic contraction of the ciliary muscle in the eye. This ciliary spasm not only leads to eye fatigue and discomfort but may also trigger myopia or exacerbate its progression. Additionally, while using smartphones, blink frequency and blink duration decrease significantly, predisposing users to eye fatigue and ciliary muscle spasm.

Smartphones are electronic devices that emit various forms of radiation. Frequent exposure to such radiation can irritate the eyes and contribute to myopia development. To prevent myopia, it is advisable to minimize screen time—especially for children whose visual systems are still developing, as excessive exposure to electronic devices significantly increases their risk of myopia. Similarly, time spent on computers or watching television should also be limited. Regular rest breaks and avoidance of visual fatigue are essential. Moreover, prolonged smartphone use may cause dry eyes.

In daily life, individuals should maintain healthy lifestyle and dietary habits. We hope this response has been helpful to you.
